The discrimination against folks that prefer to carry the mic switch on their left side is repugnant.

Besides, their button hole is so frickin' small - hard to get the mic through it. Some folks get a much larger button hole sewn into the side seam (left or right). Some folks get a large button hole sewn into the waist band of their pants for the same reason. It also lets those folks push the excess cable from switch to the transmitter through that waist band button hole, inside the pants, to conceal it.
